Moving a Smoke Simulation in Time
Locate the cache of the simulation. Per default, this would be in a subdirectory called blendcache_smoke.



Next open up the folder and find the frame index in the filename.



In my case the index is positioned at the -15th to -9th position counted from the end.


  43756265_000001_00.bphys


By simply replacing 000001 with 000011 the simulated cache of frame 1 is moved to frame 10.

Several options:


Replace all the filenames manually.
Use a third party program to rename files.
Use a python script.


This script will do what you asked for.

import os
from bpy import path

def OffsetCacheIdx(pPath, offset = 0, idx_position = [-15, -9]):
    start, end = idx_position
    idx_length = end - start
    if (idx_length &lt;= 1):
        print("Need a valid index position.")
        return

    smokedir_path = path.abspath(pPath)
    smokecache_files = []
    for (dirpath, dirnames, filenames) in os.walk(smokedir_path):
        smokecache_files.extend(filenames)

    smokecache_files = list(reversed(sorted(smokecache_files)))

    smokecache_indices = []
    # parse index to int and store in list
    for i, sc_f in enumerate(smokecache_files):
        name = sc_f[start:end]
        smokecache_indices.append(int(name))

    if (smokecache_indices[-1] - offset &gt;= 0):
        print("Negative frame values, can't do that.")
        return

    for i, file_name in enumerate(smokecache_files):
        smokecache_indices[i] += offset
        new_file_name = file_name[:start] + str(smokecache_indices[i]).zfill(idx_length) + file_name[end:]
        os.rename(os.path.join(smokedir_path, file_name), os.path.join(smokedir_path, new_file_name))

OffsetCacheIdx("//blendcache_smoke", 10)


The only line you need to change is the last line. The first parameter is the path of the folder containing the cache files, the second parameter is the offset (how many frames you want to shift the simulation).

An optional third parameter can be the position of the index in the filename.

OffsetCacheIdx("//blendcache_smoke", 10, [1, 10])
